双重立义、机械力与能力——论胡塞尔实践世界的触觉基础

胡塞尔的触觉观是常常遭到忽视的一个主题。提到现象学直观,一般会将其与视觉联系起来。但在胡塞尔的诸多文献中,视觉与触觉经常成对出现,而且他认为触觉是元感觉场,强调触感知相对于视感知的优先性,进而将触摸行为视作实践活动的基础。不过,胡塞尔的这些表述大多是零散、不完善的。本文将通过触觉的双重立义特征来探讨其元感觉场地位,引出其作为元实践场的意涵;然后着眼于元实践区域中对象和主体两个维度的原初显现,将触觉优先性放入机械力和能力如何被给予和类比的问题中进行解释,以此对触觉在实践中的基础地位做一个新的系统性阐发。     

Airport Servicescape,Approach Intentions,and the Mediating Role of Perceived Merchandise Value and Shopping Value1

Despite the large body of work on approach intentions in airport servicescapes, literature considering cognitive evaluations as a possible mediator is lacking. The aim of this study is to address this gap in literature by investigating the effect of an airport servicescape environment on approach intentions through cognitive evaluations on the foundation of the stimulus–organism–response framework. Data of 484 passengers at Chinese international airports were collected. Overall, perceived merchandise value significantly mediated the relationship between airport servicescapes and approach intentions; perceived merchandise value and shopping value acted as chain mediators between airport servicescapes and approach intentions. The theoretical implications are discussed, and the results could be used by airport stores to achieve higher approach intentions.     

Perceptual organization and apparent brightness in subjective contour figures

According to a number of theories subjective contours arise from brightness contrast and/or assimilation. The apparent brightness gradients generated by these effects are assumed to give rise to the perception of contours delineating the gradients. A study is reported in which naive observers were shown a subjective contour display and asked to report what they saw. They were then asked to judge whether the center or the surround of the display appeared brighter. Subjects whose reports indicated that they had seen the subjective contour figure showed an overwhelming preference for the center of the display being brighter than the surround. However, subjects who did not see the subjective contour figure did not differ significantly in their selection of the center over the surround. This finding presents difficulties for any theory which derives subjective contours from the apparent brightness difference.     

"大一统"视野下的历史人物观

"大一统"思想作为中华民族文化血脉中一个根深蒂固的成分,一向是中国人评价历史人物的重要尺度.无论在何种环境下,追求或顺应"一统"的人往往得到后世的好评,而企求"分裂"或满足于分裂状态的人则大多受贬斥.在通常情况下,"大一统"这一评价标准能超越人物的实际功绩、仁、和平、汉族主义和阶级意识等一系列其他的评价标准.     

The Perceptual Centre of a Stimulus as the Cue for Synchronization to a Metronome: Evidence from Asynchronies

In tasks where subjects are required to tap in synchrony to a sequence of evenly spaced uniform auditory stimuli (a metronome), tap onsets typically tend to anticipate the metronome's stimulus onsets. We investigated this phenomenon, called “negative asynchrony”, as a function of (1) the duration of the stimuli (1 or 2, 50, 100, and 300 msec), (2) the rise time of the stimuli (0%, 40%, and 80% of stimulus duration), and (3) the interstimulus onset interval duration (500, 700, and 900 msec). The results from three experiments with 28 different subjects showed a significant reduction of the negative asynchrony with longer stimulus durations, and the reduction was not significantly affected by the tempo of the stimulus sequence. Also, a prolongation of the rise time of the stimuli caused an analogous reduction of the negative asynchrony. Findings were taken to suggest that subjects use the perceptual centre rather than physical onset of stimulus as the cue with which to synchronize
